The study, … [Read more...]
3 Minutes of Sprinting Does Something 90 Minutes of Exercise Does Not
Just three minutes of sprinting may produce a molecular response that looks very different from what happens after 90 minutes of moderate exercise. Researchers at Rockefeller University compared how the body responds to exercise performed at different intensities. They found that six 30-second, all-out sprints changed nearly one-quarter of the proteins measured in the blood … [Read more...]
Exercise May Work Better For Keeping Weight Off Than Losing It
The basic principle of weight loss is straightforward: if you consume fewer calories than you burn, you’ll lose weight. In practice though, this isn’t usually so easy or simple. Alongside counting calories or eating smaller portions, many people add exercise into the equation when trying to lose weight to help tip the balance. Yet research shows that exercise may only have … [Read more...]
